A KSD thermostat, or bimetal disc thermostat, works through a bimetallic disc that bends when exposed to temperature changes. This bending causes electrical contacts to snap open or closed, regulating the temperature. The thermostat has a pre-set temperature at which the snap-action occurs, controlling heating or cooling elements to maintain the desired temperature. Once the temperature reaches the setpoint, the contacts snap back to their original state. KSD thermostats are commonly used for precise temperature control and overheating protection in various devices and appliances.
